VALVE.

Application filed March 31, 1922. Serial Nei/18,383.

To all whom 'Zt may concern.' Be it known that we, LEO F. OFLAHERT and VILLIAM L. Krniirnrnroig citizens of ther United States, and residents of the city of Elgin, county of Kane, and State of Illinois, have invented certain new and useful Improvements in Valves, of` which the following is a. specification.

This invention relates to valves, and more particularly to mixing valves for hot and cold water, or other fluids, and has for its object the provision of an improved construction of this kind, `which is simple and eective in operation.

' Another object istoprovide such a valve with positive means independent of the mixing means for sealing the valve to prevent leakage therefrom.

Other and further objects will appear hereinafter. v

The invention consists in the combinations parts hereinafter described and claimed.- l v The invention will be best understood by reference to the accompanying drawings forming a` part of this specification, and in which,

Fig. 1 is a. vertical sectional viewof the invention, showing the valve in inoperative position,

Fig. 2 is a similar vertical sectional view of the invention, showing the valve in position to admit equal amounts of different fluids to the mixing chamber,

F ig. 3 is a sectional viewV on line 3 3 of F ig. .1

Fig. 4 is a sectional view on line 4-4 of Fig.3,and V A Fig. 5 is a top plan view of the valve proper.

The invention consists of a casing 10 of any suitable material, preferably provided with suitable inlets 11 and 12, the inner ends of which are tapered as shown, and an outlet 13. The inner periphery of the casing, is preferably provided with shoulders 14 upon which may be placed a gasket 15, o-f any suitable material. Preferably seated upon gasket 15 is a partition 16 of any suitable material, suc-h partitio-n preferably having an aperture 17 therein surrounded on its under side by an annular rib 18.

Mounted in the mixing chamber 19 formed by the partition 16 is a slidable valve 20, which may be of any suitable kind, in this particular instance being in the form of a piston or disc. annular recess 21 therein, as shown, and the periphery of such vdisc is provided with 0ppositely disposed offset port-s 21 and 22, such ports communicating with the annular recess 21. bores 23, which preferably communicate with the annular recess 21, and slidably engage pins 24 in the bottom of the chamber 19 to prevent rotation of the valve in the chamber 10, but permit sliding movement therein.

Preferably mounted in the inner face of the disc 20 is a washer or packing ring 25, which is adapted to abutl against the annular rib 18 when the valve is in closed position.`

Any desirable means may be employed for imparting slidable movement to valve 20, but` we preferably provide such valve with a threaded socket-26 for the reception of the threadedend of a stem 27, which may project outwardly through the aperture 17 in the-partitionl. The outerportio-n of the stem 27 also has thread-s thereon, preferably oppositely disposed tothe threads on the lower end of the stem, and such threads en'- Such disc preferably has an The valve may be provided with f i gage-corresponding thread-s in a boss 28, prof vided on the inner face of a cylindrical mem*- ber 29, mounted in the casing 10, such stem projecting through the outer end of the member 29, and having mounted thereon a suitable handle 30 for turning the stem 27.

In operation it. will be seen that lby turn-l ing the handle sliding movement is imparted to the disc 20, initially causing the port 21 to register with the inlet 11, which permits say cold water to enter the reces-s 21 and pass from the same through the aperture 17 and be discharged through the outlet 13. Further mo-vement of the disc 20 partially closes the inlet 11 and partially opens the inlet 12, thereby permitting both hot and cold water to enter the recess 21, and pass from the outlet as before. Still further movement of the disc 20 completely closes the inlet 11 and completely opens the inlet 12 admitting only hot water. Movements of the valve to positions intermediate those described of course mixes the hot and cold water so as to obtain water of any desired temperature. Reversing the movement of the handle 30, returns the disc 20 to its original position against A cap'l32 may be threaded onto M the rib 18,-Which. prevents lealrage of Water through the mixing valves, as so frequently happens. The oppositely disposed. threads are provided for the purpose of accelerating the movement of the valve, the valve by this construction being capable of very rapidVV movement.

While We have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation and modilication Without .departing from the spirit of the invention.

mixing chamber; a mixing valve slidably mixing chamber; opposite ports in the periphery of saidvalve; a circumferential recess in said valve communicating With said ports and said mixing chamber ;l and means on said valve'r Within mounted in said ysaid` recess and adapted in operative position of the valve to close said aperture.
